What is the mechanism of the Grignard reaction?
Grignard reaction mechanism explains the addition of alkyl/vinyl/aryl magnesium halides to any carbonyl group in an aldehyde/ketone. The reaction is considered an important tool to form carbon-carbon bonds. These alkyl, vinyl or aryl magnesium halides are referred to as Grignard reagents.
How do you synthesize triphenylmethanol?
Using this Grignard reagent, triphenylmethanol can be synthesized in a two-step reaction first adding the reagent and then adding an acid. The Grignard reagent attack the electrophilic carbonyl carbon of the benzophenone and pushed electrons up to the oxygen.
What is the structure of triphenylmethanol?
C19H16O
Triphenylmethanol/Formula
Why Grignard reagent is highly reactive?
Because the carbon atom in a Grignard reagent has a partial negative charge, it resembles a carbanion, and it reacts with electrophiles. Grignard reagents are very reactive reactants that are used synthetically to form new carbon-carbon bonds.
What is the limitation of Grignard reagent?
The disadvantage of Grignard reagents is that they readily react with protic solvents (such as water), or with functional groups with acidic protons, such as alcohols and amines. Atmospheric humidity can alter the yield of making a Grignard reagent from magnesium turnings and an alkyl halide.
How do you calculate triphenylmethanol yield?
To calculate the percent yield of triphenylmethanol, you divide the actual yield by the theoretical yield and multiply by 100.

Is Triphenylmethanol soluble in water?
How is the basicity of triphenylmethanol enhanced?
On the other hand, the basicity of triphenylmethanol is enhanced due to the formation of a resonance-stabilized carbocation upon breaking of the C–O bond. After protonation of the oxygen under strongly acidic conditions, triphenylmethanol loses water to form the triphenylmethyl (“trityl”) cation.
What happens when benzophenone is mixed with triphenylmethanol?
benzophenone to form triphenylmethanol (see Figure 2). This product is a tertiary alcohol with three benzene rings, all of which are attached to a central carbon atom. Figure 2. Reaction of benzophenone with phenylmagnesium bromide (Pavia 303). There are no common uses or commercial applications for triphenylmethanol.
Which is easier to isolate trityl cation or triphenylmethanol?
The trityl cation is one of the easier to isolate carbocations, although it quickly reacts with water. The preparation of triphenylmethanol from methyl benzoate or benzophenone and phenylmagnesium bromide is a common laboratory experiment for illustrating the Grignard reaction. An alternative starting material is diethyl carbonate.
Why does triphenylmethanol have a yellow color?
In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable “trityl” carbocation. Many derivatives of triphenylmethanol are important dyes.
